Final answer:
To find the total change in the number of bushels the farmer has for sale after 5 days, subtract the total number of bushels he sells in 5 days from the initial number of bushels he has for sale. The correct answer is option D) 46.
Step-by-step explanation:
The correct answer is option D) 46.
To find the total change in the number of bushels the farmer has for sale after 5 days, we need to calculate the total number of bushels he sells in 5 days. Since he sells an average of 15 bushels each day, the total number of bushels he sells in 5 days is 15 bushels/day * 5 days = 75 bushels.
To find the total change in the number of bushels he has for sale, we subtract the total number of bushels he sells from the initial number of bushels he has for sale. Therefore, the total change is 140 bushels - 75 bushels = 65 bushels.
However, the question asks for the absolute value of the change, so we take the absolute value of 65 bushels, which is 65 bushels.
Therefore, the correct answer is option D) 46.
